Resolved issues

Here is a list of all the issues that have been resolved for this release

Bug (49)

CAMEL-25715

camel-jbang - camel cmd eval breaks an expression with a double quote or a slash

CAMEL-25638

camel-graphql - bind accessToken and basic credentials to the configured httpUri authority

CAMEL-25629

camel-jbang - java version enum should include 25

CAMEL-25620

camel-console: ConcurrentModificationException in DefaultDevConsoleRegistry.doStart when camel-cli-connector is enabled

CAMEL-25603

camel-pqc - key encapsulation operations share one KeyGenerator and KeyAgreement instance across concurrent exchanges without synchronization

CAMEL-25601

camel-vertx-websocket - a client consumer started while the WebSocket is already open registers no handlers

CAMEL-25582

camel-vertx-websocket - a consumeAsClient consumer starts overlapping reconnect attempts: after a slow handshake it holds up to 20 WebSockets and routes every message once per WebSocket; it also keeps reconnecting after its route is stopped

CAMEL-25559

camel-core - with the pooled exchange factory, an exchange that a consumer gives back without routing it is put into the pool twice, and the next two messages share one exchange

CAMEL-25558

camel-aws2-s3 - a listed object that cannot be got (deleted meanwhile, or a failed get) fails the poll and stays in the in-progress repository, so it is never consumed until a restart

CAMEL-25534

camel-mail - subject option description still says the Subject header takes precedence, but useHeaderSubject defaults to false

CAMEL-25533

camel-jbang - camel run ignores camel.server.port (and the other camel.server.* settings) for the HTTP server started for platform-http unless camel.server.enabled=true

CAMEL-25494

camel-yaml-io - YAML route dump writes routeConfiguration onException items without their onException key, which neither the schema nor the loader accept

CAMEL-25490

camel-jbang - camel validate normalize writes a top-level onException into the steps of every route, which the YAML DSL schema rejects

CAMEL-25486

camel-http - the OAuth2 token request with a resource indicator sends only the resource parameter

CAMEL-25452

camel-jbang - camel export ignores --resource-dir, the directories never reach the exported project

CAMEL-25437

camel-jbang - camel run --prop key=value with a space is silently ignored

CAMEL-25427

camel-support - on-demand route reload fails with FileNotFoundException after a route file is removed from the source dir

CAMEL-25418

camel-jbang - camel get vault does not list the Kubernetes config map names

CAMEL-25376

camel-netty-http - match security constraint roles by exact role name

CAMEL-25375

camel-undertow - Apply securityProvider, allowedRoles and handlers to WebSocket endpoints consistently with HTTP endpoints

CAMEL-25227

camel-azure-eventhubs: partition header conflict and no default header filter

CAMEL-25224

camel-xslt / camel-xslt-saxon: implicitly converted DOM sources select wrong XSLT context node

CAMEL-25222

Route dump - YAML with source locations loses the list dash of a choice when, and throwException given an exception instance is dumped empty

CAMEL-25164

camel-infinispan - the aggregation repositories recover a completed exchange without the message that completed the group

CAMEL-25116

camel-main - /q/download?classpath=true does not list project resources

CAMEL-25103

camel-vertx - Client authentication, cipher suites and protocols of SSLContextParameters are not applied

CAMEL-25086

camel-platform-http-starter: fails to start outside a servlet web application (ServerProperties/WebMvcProperties)

CAMEL-25085

Rest DSL: under json/xml binding a response without Content-Type ignores the verb's produces

CAMEL-25023

camel-util - IOHelper.copy counts copied bytes in an int, so zipFile/tarFile maxDecompressedSize values of 2 GiB or more are not enforced

CAMEL-25001

camel-core - Supervising route controller: an exhausted route stays unhealthy after it is started manually

CAMEL-25000

camel-ai-tool / camel-ai-resource - tools and resources are missing when a route sends a request as soon as it starts

CAMEL-24973

camel-util - URISupport.sanitizeUri does not follow the endpoint URI parser for RAW values, userinfo, dash-case option names and additional keywords

CAMEL-24940

camel-jbang/cli - autodetection of Kubernetes property placeholder functions (configmap:, secret:) stopped working in 4.22.1

CAMEL-24935

camel-pulsar - the producer replaces the message body with the MessageId

CAMEL-24932

camel-pulsar - the polling loop dies on a NullPointerException when a receive fails

CAMEL-24889

camel-debezium - the consumer is never told that the embedded engine has failed

CAMEL-24887

ManagedRouteGroupMBean exchange stats changed

CAMEL-24848

camel-mail - The useHeaderFrom and other useHeaderXXXXX options defaulted to false but the document said the default should be true

CAMEL-24816

camel-elasticsearch/camel-opensearch: minor robustness fixes (scroll clear NPE, id header clobber, size/from header bleed)

CAMEL-24814

camel-elasticsearch/camel-opensearch: BulkRequestAggregationStrategy returns the wrong exchange, breaking bulk aggregation

CAMEL-24811

camel-servlet - async=true without executorRef completes the AsyncContext before a truly-asynchronous route finishes

CAMEL-24799

camel-jbang: Installing Camel Kit by command name loses the requested plugin version

CAMEL-24776

camel-jbang run does not auto-load camel-kubernetes for secret property functions

CAMEL-24766

CAMEL-24691

camel-saxon - align XQueryBuilder with secure XML parsing defaults

CAMEL-24594

RestBindingAdvice response marshalling failure is silently swallowed

CAMEL-24590

ManagedRouteGroupMBean.getFailuresHandled() / getLastExchangeFailureHandledTimestamp() return 0/null even though a member route recorded a handled failure

CAMEL-24440

camel-crypto - CryptoDataFormat validates the MAC after decrypting, reuses the cipher key for the HMAC, and has no per-message IV

CAMEL-24371
